Mel B 'going on secret dates with former girlfriend Christine Crokos'...after revealing past fling with fellow Spice Girl Geri Horner 

Mel B is said to be going on secret dates with her former girlfriend Christine Crokos.

The pair have been sending each other flirty messages on social media lately and look set to be going on a dinner date.

The Spice Girl, 43, recently shared a snap of herself on Instagram in underwear and a headband with film producer Christine leaving a comment.

She wrote: 'Oh boy! Don’t be bringing that out to dinner with me! Hahaha.'

Mel responded by saying, 'stop it' while another friend commented saying she should wear the headband on their date.  

A source told the Mirror: Mel still has a strong connection with Christine even though it's been more than 10 years since they broke up. 

Mel and Christine dated for several years before they parted ways in 2006.

Speaking previously about their relationship to Gay Star News, the singer said: 'It wasn’t experimentation. I fell in love with a woman for five years. An experiment doesn’t last five years.'

It comes soon after Mel said on Piers Morgan's Life Stories that she and her Spice Girls bandmate Geri Horner had previously slept together.

In the clip, Piers is seen asking Mel: 'You were coming here to be brutally honest - did or didn't you sleep with Geri Halliwell? Did you sleep with her?'

Looking bashful, Mel at first tries to dodge the question, telling Piers: 'Yeah. We all slept in a bed together, but not like that, all of us.'

But Piers was relentless, asking: 'Did you sleep with Geri like that?' to which Mel smiles and nods as a shocked Piers checks, 'Yes? Really?'

'She's going to hate me for this because she's all posh in her country house with her husband,' said Mel of Geri, who is married to Formula 1 team boss Christian Horner.

The mother-of-three also detailed her night of passion with the Lift Me Up hitmaker on 2Day FM's Grant, Ed and Ash.

Mel shared: 'I actually didn't really admit to anything... I just admitted we had a little bit of a thing back in the day and that's it. It happened one night!'

While it was claimed that the America's Got Talent judge's comments caused a rift among the Spice Girls ahead of their tour, Mel told the radio station they are doing just fine.

'I was on the phone with Geri. It was all tongue in cheek and I didn't go into detail,' she said, adding the band is still going ahead with their scheduled tour.

'I texted her and said I admitted on Piers that we had a little thing so don't worry about it, it was all tongue in cheek.

'I didn't go into detail and it was pre your husband and pre your babies and mine. We had a long conversation. She texted me the night of and then we spoke at length.

'I don't now why everyone is making such a big deal about it!'
